RESUMO

BACKGROUND: Boys with posterior urethral valves (PUVs) have an increased risk of febrile urinary tract infections (fUTIs). Circumcision is believed to reduce the risk of fUTIs in boys, although there are no randomized trials demonstrating this. OBJECTIVE: To determine the effect of circumcision on the risk of fUTIs in boys with PUVs. DESIGN, SETTING, AND PARTICIPANTS: A clinical randomized trial that ran between August 2012 and July 2017 was conducted. The trial was multicentric, including 13 referral centers for pediatric urology. Male boys, aged 1-28 d, diagnosed with posterior urethral valves, confirmed by voiding cystogram, were included. The exclusion criteria included presence of a genital malformation contraindicating performing a circumcision. INTERVENTION: Participants were randomized to neonatal circumcision + antibiotic prophylaxis (CATB) or antibiotic prophylaxis alone (ATB), and followed for 2 yr. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: The primary outcome was a risk of presenting fUTIs in each group. An fUTI was defined as fever (>38.5 °C) with evidence of pyuria and culture-proven infection on urinalysis, obtained by urethral catheterization or suprapubic aspiration. A bivariate analysis of the primary outcome was performed using the Kaplan-Meier method. RESULTS AND LIMITATIONS: In total, 91 patients were included: 49 in group CATB and 42 in group ATB. The probability of presenting an fUTI was 20% in group ATB versus 3% in group CATB. The hazard ratio of presenting an fUTI within 2 yr in the ATB group compared with that in the CATB group was 10.3 (95% confidence interval: 1.3-82.5). Sixty-four children (70.3%) had a complete follow-up at 2 yr of age. CONCLUSIONS: Circumcision significantly decreases the risk of presenting an fUTI in boys with PUVs. PATIENT SUMMARY: In this report, we compared, in a multicentric trial, the number of febrile urinary tract infections (UTIs) in boys with posterior urethral valves who had either antibiotic prophylaxis alone or antibiotic prophylaxis and circumcision. We found that those who had a circumcision had a significantly lower risk of febrile UTIs.

RESUMO

INTRODUCTION: Paediatric recurrent epididymitis is frequently observed in several urogenital conditions, and may result in deterioration of long-term fertility. The management of recurrent epididymitis is still a therapeutic challenge for paediatric urologists, and as yet there is no consensus for treatment. OBJECTIVE: To present a minimally invasive endoscopic approach for the treatment of recurrent epididymitis (more than three episodes). PATIENTS AND METHODS: Eleven boys were referred with a history of recurrent epididymitis in a context of urogenital malformations. All children underwent endoscopic transurethral injection. Dextranomer/hyaluronic acid was injected around the ejaculatory ducts at the verumontanum (Summary Fig.). The medical records and outcomes of the patients were retrospectively reviewed. RESULTS: Of the 11 boys, two (18%) had a history of bladder exstrophy, three (27%) anorectal malformation, two (18%) peno-scrotal hypospadias, two (18%) posterior urethral valves, one (9%) seminal vesicle cyst, and one (9%) urethral stricture. The median age at injection was 3.75 years (range 8 months-14.7 years). Endoscopic injection effectively prevented recurrence in eight patients (73%) with a mean follow-up of 3 years (range 6 months-8.8 years). The mean injected volume was 0.7 ml/session. No perioperative complications were recorded. Vas clipping was performed in three patients after unsuccessful injections. DISCUSSION: The current discussion for management of recurrent epididymitis is mainly based on vas clipping. Endoscopic injection in the verumontanum could offer several potential advantages over vas clipping; moreover, it is easy to perform for an urologist who usually uses endourological approaches. It is believed that only Kajbafzadeh et al. have reported their experience with endoscopic injection in the verumontanum in seven patients with structural anomalies, and they had a 42% success rate. Similarly, the current study did not observe perioperative or postoperative complications. CONCLUSION: In this series, endoscopic injection of the verumontanum was considered to be a safe and effective treatment in almost 73% of children with recurrent epididymitis. It did not result in perioperative complications and not contraindicate a subsequent surgical procedure such as vas clipping.

RESUMO

INTRODUCTION: Despite many advances, the management of renal stones - especially lower caliceal stones (LCS) - remains a challenge. The gravity-dependent location of the lower calices hinders the spontaneous clearance of fragments, which can be a nidus for future growth and symptomatic recurrence. Currently, there is no standard adjunctive therapy to facilitate fragment passage. OBJECTIVES: To report the safety and effectiveness of mechanical percussion diuresis and inversion (PDI) therapy for eliminating renal stones in children. PATIENTS AND METHODS: Since November 2013, children with residual fragments (after shock wave lithotripsy or flexible ureteroscopy) or native symptomatic renal stones were prospectively included in a protocol of four PDI sessions. After giving written consent, the children drank 10 ml/kg of water 30 min before therapy. They then laid in a prone Trendelenburg position on a couch angled at 45° and received continuous 10-min mechanical percussion applied over the affected flank by a physiotherapist (Figure summary). Tolerance stone burden reduction and stone clearance were documented with ultrasound 4 weeks after the last session. RESULTS: Seventeen participants, with a median age of 10.8 years (range 18 months to 18 years), received 82 PDI sessions performed over 22 months. The median stone diameter was 5 mm (range 3-9). All children tolerated the PDI therapy well. Over a median follow-up of 11 months (range 3-18), no significant adverse effects were noted. The overall stone-free rate was 65%. Four of the six patients with residual fragment passed their fragments. The patients who did not become stone free by PDI experienced a decrease in fragment size of 57% (range 34-71). The observance rate was 100%. DISCUSSION: Many studies have demonstrated that the gravity-dependent position of the lower calyces appears to be an important factor limiting the clearance of LCS. Positioning patients with a degree of inversion in order to put the collecting system beyond the horizontal plane affected the LCS through gravitational force. Complications were rare. PDI appeared to save costs and have similar success rates as shock wave lithotripsy for native small renal stones in children. CONCLUSION: PDI is safe and effective for facilitating gravity-dependent drainage of renal stones and provides an opportunity to treat children in a quick, non-invasive, economic, painless, non-radiative and diverting fashion. This therapy is a valuable alternative in the pattern of stone management. In case of persistent fragments, it is recommend that the number of sessions be increased to six.

RESUMO

OBJECTIVE: Evaluate neonatal management and outcome of neonates with either a prenatal or a post-natal diagnosis of EA type III. STUDY DESIGN: Population-based study using data from the French National Register for EA from 2008 to 2010. We compared children with prenatal versus post-natal diagnosis in regards to prenatal, maternal and neonatal characteristics. We define a composite variable of morbidity (anastomotic esophageal leaks, recurrent fistula, stenosis) and mortality at 1 year. RESULTS: Four hundred and eight live births with EA type III were recorded with a prenatal diagnosis rate of 18.1%. Transfer after birth was lower in prenatal subset (32.4% versus 81.5%, P<0.001). Delay between birth and first intervention was not significantly different. Defect size (2cm vs 1.4cm, P<0.001), gastrostomy (21.6% versus 8.7%, P<0.001) and length in neonatal unit care were higher in prenatal subset (47.9 days versus 33.6 days, P<0.001). The composite variables were higher in prenatal diagnosis subset (38.7% vs 26.1%, P=0.044). CONCLUSION: Despite the excellent survival rate of EA, cases with antenatal detection have a higher morbidity related to the EA type (longer gap). Even if it does not modify neonatal management and 1-year outcome, prenatal diagnosis allows antenatal parental counseling and avoids post-natal transfer.

RESUMO

Mild head trauma can be associated with concussion, defined as transient brain function impairment without radiological findings. Sports-related concussion is also reported in pediatrics (rugby, ice hockey, football, boxing, etc.). Misdiagnosis can lead to persistent neurocognitive signs with athletic and academic problems. Consensual tools are available, but they are not well-known by first-line doctors, coaches, and patients or parents. Concussed players should not be allowed to return to the field on the same day. Return to play should be gradual over 3weeks or more. School activities may need to be modified to favor cognitive rest. Prevention is based on risk information and knowledge transfer, rule changes, and protective helmets, whose effectiveness is not always proven.

RESUMO

OBJECTIVE: Antibiotic administration during acute appendicitis in children continues to be debated. The purpose of this study was to compare efficacy of two prophylactic antibiotic treatment guidelines in acute appendicitis and peritonitis in children. MATERIEL AND METHODS: The infectious complication rate after appendicectomy was compared during two distinct periods (before/after study). During the first period, the guidelines for antibiotic administration were based on ticarcillin-clavulanic acid. During the second period, the guidelines were based on amoxicillin-clavulanic acid for non-perforated appendicitis or appendicitis with localized peritonitis, and clavulanic acid was reserved for general peritonitis. All children younger than 16 years of age who underwent appendicectomy during the periods studied were included. Data were retrospectively collected from surgical and anesthetics charts. RESULTS: Ninety-five children during the first period and 238 during the second were included. In the children with non-perforated appendicitis, no postoperative infectious complication occurred in 74 children during the first period versus two out of 153 (1%) during the second period. In cases of perforated appendicitis, postoperative infectious complications occurred two cases (10%) during the first period versus nine (11%) during the second. There were no significant differences between the two periods. CONCLUSION: In this population, antibiotic administration guidelines based on amoxicillin-clavulanic acid for stages I-III of appendicitis maintained a low rate of postoperative infectious complications and were not associated with a higher postoperative infectious complication rate than guidelines based on ticarcillin-clavulanic acid.

RESUMO

Recurrent tracheoesophageal fistula (TEF) is possible after repair of congenital esophageal atresia. The frequency of recurrent TEF is observed in about 10% of the cases. Within a cohort of 67 children with type III esophageal atresia repaired between 1998 and 2009, we aimed to identify the number of children with recurrent TEF, the risk factors for this condition, and the treatment proposed. The sex ratio was 1.7. Surgery was performed between 4 and 36 hours of life. Five children (7.5%) had a recurrent TEF, usually during the first 3 months, revealed by respiratory symptoms related to feeding in some cases. We noted that recurrent TEF was more frequent with anastomotic leakage (P=0.09) or postsurgical pneumothorax (P<0.01). The diagnosis was made in four cases out of five by a methylene blue test performed during a tracheobronchial endoscopy. Surgical treatment was noted in four children, with three postsurgical secondary effects. One child was treated by endoscopy and an esophageal clip. With a median follow-up of 52 months, no recurrence was noted. The recurrence of TEF may be linked to postsurgical events. Diagnosis is not easy and treatment is not clearly codified. Endoscopic treatment may be an advantageous option to surgery, likely with less morbidity.

RESUMO

The aim of this study was to evaluate the medium-term outcome (health status, medical and surgical French National Health Authority-recommended follow-up, and quality of life) of children born with type III esophageal atresia (EA). Previous events (during the perinatal period, associated abnormalities, respiratory and digestive complications) of children treated for type III EA at the Marseille university hospitals between 1999 and 2009 were noted. Parents completed a standardized questionnaire concerning the health of their children during the previous year, and a quality-of-life questionnaire (PedsQL 4.0) was also completed by children aged more than 8 years. Among the 68 children treated, 44 responded to our solicitation (mean age, 7.6 years; range, 3-12.8 years). Previous important events were : pneumonia(s) (65%), asthma before the age of 3 years (66%), hospitalization for a respiratory event (45%), fundoplication (20%), and esophageal dilatation (45%). We noted current chronic cough (16%), asthma (30%), dysphagia (39%), and symptomatic gastroesophageal reflux (9%). National guidelines were not respected, except for the surgical indications in children aged less than 6 years. The quality-of-life scores (n=43 children) were similar to healthy controls but were negatively influenced by a gastrostomy procedure (P=0.020), pneumonia (P=0.013), and hospitalization due to a respiratory event (P=0.006) or a digestive event (P=0.010), and also by current asthma (P=0.004). In conclusion, despite recurrent respiratory or digestive symptoms and inadequate recommended follow-up, the quality of life of children treated for type III of EA is good.

RESUMO

Paratesticular rhabdomyosarcoma is a rare and highly aggressive embryonal tumor in infancy and childhood. The tumor is intrascrotal, localized in the spermatic cord, the epididymis, or in the tunica vaginalis. Rhabdomyosarcoma represents 10% of testicular tumors of infancy. On physical examination, a painless scrotal tumefaction is observed. A surgical and pathological classification is used to group patients according to the extent of residual tumor after the initial surgical procedure: Intergroup Rhabdomyosarcoma Study classification (IRS). Multimodality therapy involving surgery, chemotherapy, and radiotherapy is necessary. Depending on the extent of disease and the staging group, the approach of treatment is different. The most important factors affecting treatment outcome are the stage, the pathological subtype of the tumor, and the age of the patient. Younger patients (<10 years) with a local tumor and with embryonal pathology have an excellent prognosis. We report the case of a 6-year-old boy admitted for a specialist consultation because of the recent appearance of a tumor in the right scrotum. On physical examination, a painless, solid, right scrotal mass was noted and the diagnosis of paratesticular rhabdomyosarcoma was made. This diagnosis can be suspected on physical and on ultrasound examinations, but only a pathological examination will confirm it. The authors discuss the therapeutic issues raised by this lesion and report one case of paratesticular rhabdomyosarcoma.

RESUMO

Post-traumatic small-bowel obstructions are rare and late complications following blunt abdominal trauma. Timely diagnosis is frequently impeded because of nonspecific associated symptoms, and furthermore, the degree of urgency is frequently underestimated due to the accidental cause. During the last 6 years (2005-2011), we have observed only 2 cases (4 and 10 years old) with post-traumatic small-bowel obstruction. On admission the patients had a contusion on the abdominal wall, duodenal hematoma and a Chance fracture of the lumbar spine on the computed tomography (CT) scan. Although early clinical improvement was noted, progression of the disorder was observed for the following 15 days like an occlusive syndrome (abdominal distension, nausea, emesis). Abdominal ultrasound and computed tomography scan revealed small-bowel obstruction. At laparotomy, jejunal stenosis was found associated with mesenteric tears, which was resected with end-to-end anastomosis. Six to 8 months of follow-up ascertained the therapeutic efficacy of the procedure. Post-traumatic small-bowel obstructions are rare; the clinical presentation is unspecific and appears with a time lag following the trauma. Echography and computed tomography scan can establish both the diagnosis and therapeutic choice.

RESUMO

AIMS: To analyze the results of treatment of major renal injuries according imaging data in order to determine their function after follow-up. PATIENTS AND METHODS: This is a retrospective study of 22 cases of fracture of the kidney (grade V) in two pediatric surgical services that were reviewed over a period of 16 years. After initial conservative treatment in 19 patients (86.5%), a scan and/or Uro-MRI were realized in all patients in monitoring evolving. Three children with vascular injury were treated by interventional radiology. The morphology and functional evolution of the injured kidney were determined. RESULTS: A DMSA scan investigation was performed in 21 patients (95.5%) associated with Uro-MRI in two cases; one patient was only explored with Uro-MRI. A complete restitution of the renal parenchyma was confirmed in 10 children (45.5%), we noted an atrophy of the upper pole in 30%, a lower pole atrophy in 4.5%, two complete renal atrophy in 9%. An urinoma was present in six patients (27%) that required drainage in five cases and declined during the surveillance in one case. Normal function of the injured kidney was noticed in half of grade V (11 of 22 patients) with a mean follow-up of 19 months. None of our patients did present hypertension. CONCLUSION: Non-operative conservative treatment in severe renal trauma was efficient, morphological and functional sequelae were present in 50% on scintigraphy and/or Uro-MRI.

RESUMO

We report a case of a renal mass in a 4-month boy, which occured during the assessment of a pelvi-calyceal dilatation diagnosed at 23 weeks of gestational age. There was no history of urinary infection, fever or weight loss. Physical examination revealed a mass of the left flank with significant flank tenderness. Laboratory test showed a biological inflammatory syndrome and urine culture was negative. Investigations including ultrasound and computed tomography scan were suggestive of diffuse xanthogranulomatous pyelonephritis with a non-functioning left kidney. Left total nephrectomy was performed through a lumbar incision with an extraperitoneal approach. The kidney was enlarged with a dilated pelvis containing pus upstream of a proximal ureteral atretic segment. Pathological examination of the kidney confirmed the diagnosis of diffuse xanthogranulomatous pyelonephritis. The boy remains well at 1 year follow-up. Xanthogranulomatous pyelonephritis is very rare in infants. It is an uncommon severe progressive renal infection resulting in destruction of renal parenchyma, histologically replaced by xanthomatous cells and granulomatous reaction. Pathogenesis of xanthogranulomatous pyelonephritis remains unclear. But it is well known that urinary tract obstruction and renal lithiasis are determining factors. It can occur in variant clinical forms but its symptoms remain non-specific. Curative treatment consists in nephrectomy and definitive diagnosis is made on histological examination of the kidney. This diagnosis should be discussed when a renal mass occurs in a context of malformative uropathy and xanthogranulomatous pyelonephritis have to be included in the differential diagnosis of renal mass in infants and children.

RESUMO

We report a newborn aged 19 days, carrying a posterior urethral valve antenatal screening in which developed 7 days after the entire section of the valve, a compressive urinothorax in connection with a perirenal urinoma. Pleural and bladder drainage has a surrender of effusions and a healing of the renal parenchyma. The thoracic urine effusion is a very rare complication of a posterior urethral valve with perirenal urinoma. This probably results from a rupture of a fornix dysplastic by hypertension of the urinary tract. The authors emphasize the unusual discovery of this disease by breathing problems and his delayed character after resection of the obstruction in the neonatal period.

RESUMO

AIMS: Study the incidence, type and outcome of traumatic ischemic arterial lesions of the kidney in multiple trauma patients. MATERIALS AND METHODS: Retrospective study of 500 multiple trauma patients who underwent whole body 64 slice CT Scan (mean age 34 years old, sex ratio 4M/1W, mean ISS 29). RESULTS: There were seven cases of vascular lesions of the left kidney 1.4% of patients (men, median age 25 years old, mean ISS43.9). These were closed traumas with sudden deceleration and dissection of the renal artery trunk in three cases and injury to its branches in four cases with preserved excretion. Three patients died of associated injuries, including one patient who received a stent on D0. One patient underwent a nephrectomy and the three other patients were not treated which did not affect renal function or pressure (follow-up 19 months). CONCLUSION: We found a high incidence of traumatic renal dissection in multiple trauma patients. Multidetector scan appears to provide the best results for the diagnosis of these lesions as well as the many associated lesions resulting in a very poor prognosis for these patients. Treatment is not well defined and management of these lesions is often of secondary importance because of the severity of associated injuries.

RESUMO

BACKGROUND: Gastrointestinal motility is dependent on neural influences that largely involve the enteric nervous system (ENS). The main motor patterns that occur in the fasted and fed state are noticeably different in children compared with adults. Although the development of the ENS continues after birth, there is no data on the contractile activity of segments of small intestine from young children. This study was designed to provide data on the development of muscle control by the human ENS with particular attention to acetylcholine (ACh) and nitric oxide (NO) as the primary neurotransmitters of enteric motor neurons, respectively. METHODS: Small intestinal specimens were obtained from 11 children and six adults undergoing surgery for various diseases. The mechanical activity of the circular muscle was recorded in vitro. The effects of N(ω)-nitro-L-arginine methyl ester hydrochloride, an inhibitor of NO synthesis, and of atropine, an antagonist of muscarinic receptors, were tested on the spontaneous motility and responses to nerve stimulation. KEY RESULTS: Spontaneous motility was observed in all preparations. Responses to nerve stimulation were identical in child and adult. No tonic cholinergic excitation of small intestinal motility was observed either in child or in adult. Inhibition of NO synthesis induced a major disinhibition of motility in child but not in adult. CONCLUSIONS & INFERENCES: Spontaneous intestinal motility and cholinergic and nitrergic neurotransmission are present from birth. NO provides a tonic inhibition of intestinal motility only in child. Our study indicates that NO may be a major player in shaping the ontogenic development of intestinal motility in human.

RESUMO

We present a case of a 4-month-old boy with a right abdominoscrotal hydrocele associated to a compression of the femoral triangle, causing an unilateral leg edema. Abdominoscrotal ultrasound revealed a fluid collection with abdominal and scrotal components, communicating through the deep inguinal ring. Sagittal views of magnetic resonance imaging (MRI) showed a dumbbell-shaped hydrocele and the angio-MRI venous sequences confirmed the compression of the right iliac vessels. Curative treatment was surgical through an inguinal approach and consisted in high ligation of the processus vaginalis and hydrocelectomy. Abdominoscrotal hydrocele is an uncommon pathology, which rarely occurs in pediatric population. This diagnosis should be discussed when a cystic abdominal mass is associated to an ipsilateral scrotal hydrocele. The abdominal component of the hydrocele can result in compression of adjacent structures (iliac vessels, ureter). Surgical treatment is recommended. Epididymal and testicular abnormalities are frequently described, as in our observation, and the effects on the future fertility are unknown.

RESUMO

Paediatric surgeons and urologists are often asked to evaluate boys with acute scrotal pain and inflammation. Although, there is much aetiology for this syndrome: testicular torsion, appendicular testicular torsion, epididymo-orchitis, hernia, hydrocele, trauma, Henoch-Schonlein purpura, idiopathic scrotal edema. However, testicular torsion should be at the top of the list because of the medico legal aspects. It is the one diagnosis that must be made accurately and rapidly, if there is any hope for testicular salvage. Color Doppler ultrasound scan can reliably identify those children, who required exploration and spare medical causes. The purpose of this article is to update/review the appropriate evaluation and management of the acute scrotum and to guide the clinician in distinguishing testicular torsion from the other conditions that commonly mimic this surgical emergency.

RESUMO

UNLABELLED: The purpose of this study was to determine the clinical significance of children presenting with malrotation to develop treatment recommendations. METHODS: Records of children undergoing a Ladd procedure were identified in the pediatric patient database from 1 June 1996 to 31 March 2007. Patients with intestinal obstruction caused by isolated intestinal malrotation were included. The exclusion criteria were the association of predisposing factors (omphalocele, gastroschisis, diaphragmatic hernia). Patient characteristics, imaging investigations, operations performed, and morbidity were evaluated. RESULTS: Eleven children (7 boys and 4 girls) underwent a Ladd procedure at the median age of 14 days. Seven patients presented bilious vomiting, alimentary vomiting associated with weight loss (2 cases), and melena (1 patient) at admission. The upper gastrointestinal radiological investigations established the diagnosis of intestinal malrotation in 6 cases confirmed by ultrasonography in 3 cases. Isolated Doppler ultrasound investigation was sufficient in 4 cases before abdominal surgery. In 1 case, preoperative diagnosis of intestinal malrotation was not made. Intraoperative anomalies were midgut volvulus in 7 cases, Ladd bands in 3 patients, and malrotation with intestinal ischemia in 2 cases with spontaneous resolution of midgut volvulus. Incomplete intestinal malrotation (180 degrees) was found in 10 cases and a mobile cecum in 1. CONCLUSION: These findings provide support for performing early diagnosis of intestinal malrotation to prevent the rare but potentially devastating complications of this anomaly.
